Electrical feedthrough with a sintered electrical connection

Abstract

One aspect relates to an apparatus including a first frame, a further frame, a first element, a second element, and a third element. The first frame frames the further frame, the further frame frames the first element, and electrically insulates the first element and the first frame from each other. The first element is electrically conductive, the second element is electrically conductive, and the third element provides an electrically conductive connection between the first element and the second element, and has a porosity in the range of 0.001 to 0.4.

What is claimed is: 
     
       1. An apparatus comprising a first frame, a further frame, a first element, a second element and a third element;
 wherein 
 a) the first frame frames the further frame; 
 b) the further frame
 i) frames the first element, and 
 ii) electrically insulates the first element and the first frame from each other; 
 
 c) the first element is electrically conductive; 
 d) the second element is electrically conductive; 
 e) the third element
 i) provides an electrically conductive connection between the first element and the second element, and 
 ii) has a porosity in the range of 0.13 to 0.2; 
 iii) comprises Ag in an amount in the range of 10 to 100 wt. % based on the weight of the third element; and 
 iv) has a layer thickness in the range of 0.2 to 0.6 mm. 
 
 
     
     
       2. The apparatus of  claim 1 , wherein the first element comprises a cermet. 
     
     
       3. The apparatus of  claim 1 , wherein the further frame comprises a ceramic. 
     
     
       4. The apparatus of  claim 1 , wherein the further frame and the first element are configured in one piece. 
     
     
       5. The apparatus of  claim 1 , wherein the second element is selected from the group composed of an electrical contact, a conductive path, a wire, a socket, and a plug, or a combination of at least two of these devices. 
     
     
       6. The apparatus of  claim 1 , wherein the apparatus further comprises an electrotechnical filter and wherein the first element or the second element or both is connected to the electrotechnical filter. 
     
     
       7. The apparatus of  claim 1 , wherein the third element has a porosity in the range of 0.13 to 0.16. 
     
     
       8. An implantable electrical medical device comprising a housing and the apparatus of  claim 1 ;
 wherein the housing comprises a housing opening; 
 wherein the first frame has been fitted into the housing opening. 
 
     
     
       9. A method for producing an implantable electrical medical device comprising a housing comprising a housing opening, wherein the method comprises a method step of inserting the apparatus of  claim 1  into the housing opening such that the housing opening contains the first frame.
